When you....... I feel.....

Are you using this formula to express your feelings like fears, sadness and worries to your close friends, boyfriends / girlfriends or spouse and parents? It was my first time to hear this formula when I first come to United States. I have a friend who are using this to her husband. She will say, "When you do not go home early, I feel fear, If you do it again, I will take 15 minutes time out and if you do it again, I will take 30 minutes time out and so on and so forth.
